Table 3 Experimental values of the exponents of power k for the diameters D of indenters
From: An attempt to unify the Brinell, Janka and Monnin hardness of wood on the basis of Meyer law
Indenter | Wood sample | Exponent of power k | Average k | k ≈ |
|---|---|---|---|---|
Ball | Beech (sample C) | − 0.465 | − 0.510 | − 0.5 = − 1/2 |
Beech (sample D) | − 0.554 | ± 0.045 | ||
Cylinder | Beech (sample C) | − 0.523 | − 0.553 | − 0.5 = − 1/2 |
Beech (sample D) | − 0.583 | ± 0.030 |
